UNITED STATES HOMER K. DAVIDSON, OF PRINCETON, TEXAS.

KNEE PAD.

Application filed September a; 1924. Serial No; 735,631.

To all whom it may concern:

Be it known that HOMER K. DAVIDSON, a citizen of the United States,residing at Princeton, in the county of Collin and State of Texas, hasinvented certain new and useful Improvements in Knee Pads, of which thefollowing is a specification.

This invention relates to kneeling pads for use of workmen or laborerswhose occupation necessitates kneeling and is especially designed forthe purpose of providing a de vice which may readily be attached to theknee and which when attached will permit the wearer to move freely aboutfrom place to place.

It is a further feature of this invention to provide a device which whenattached, will permit bending or flexing of the knee, and further theprovision of a device wherein a flexible knee support is capable ofbeing placed under adjustable tension.

WVith these and other objects in view, my invention consists in thenovel features of construction, combination and arrangement of parts aswill be hereinafter referred to and more particularly pointed out in thespecification and claims.

Referring" to the drawings wherein for the purpose of illustration isshown the preferred embodiment of my invention,"

Figure 1 is a view of the device as applied to the knee of the wearer,

Figure 2 is a side elevation of the knee pad, the forward end being bentas would appear on the knee,

Figure 3 is a bottom plan view of the knee pad showing the means foradjusting the tension of the pad,

Figure 1 is a transverse section taken on line H of Fig. 2, and 4 Figure5 is a plan view of the blank of leather or like material, the dottedlines inclicating where it is bent around the frame.

In describing the invention, I shall refer to the drawings, in whichsimilar reference characters designate corresponding parts throughoutthe several views, and in which 2 designates generally a main metallicframe, including side members 3, the front and rear ends of which areturned or bent downwardly to provide legs 4 and 5, the feet 6 and 8 ofwhich support respectively, transverse rods 9 and 10 upon which arejournaled casters or rollers 11 and 12.

As shown in plan view in Figure 3, the side frame members convergerearwardly, so

ditional function of properly spacing the side frame members.

Pivotally supported upon the forward elevated end of'the main frame 2,at approxiiately the junction of the upper portion of the forward legs 4with the side frame members 3 as at 14:, is a substantially U-shapedmetallic frame 20, the lower ends of the arms 15 of which are pivotallymounted at the aforesaid junction point 14 by means of pivot pins orrivets 16, and as shown in Figure 2, the arms 15, intermediate theirends are curved rearwardly as at 18 for purposes to be later described.As shown particularly by dotted lines in Figure 3, the upper ortransverse portion 19 of the frame 20 is bowed outwardly as at 21 forthe purpose as illustrated in Figure 1, of conforming to the shape ofthe leg of the user, above the kneejoint, while the curved portions 18lie upon opposite sides of the leg above the knee-joint, and with thebowed portion 21 serve in properly supporting and positioning the devicewhen in use.

Stretched across the frame members 2 and 20, is a pad 22 formed ofleather or other suitable material, said pad preferably taking the formof the blank shown in Figure 5 and including a forward portion 24 and arear portion 25, the former being turned at the folds 26 over the frame20 and the folds 28 of the rear portion being folded over the sidemembers 3 of the frame 2, the folds 28 being adjustably secured at theirfree edges by a lacing 30. The continuity of the lateral portions of thefolds are interrupted by notched portions 31 and 32 which respectivelypermit the pad to be folded around the frame members. Stitched, orotherwise secured to the upper face of the leather pad 22, is a sheet offelt or other suitable soft material 38, the pad and felt sheet togetherproviding a yielding support for the knee of the wearer, the devicepermitting at the same time, flexing or bending of the knee due to thepivotal connection of the frame 20 with the main frame 2.

To assist in securing the device upon the knee, as shown clearly inFigure 1, the forward pivoted U-shaped frame is provided with straps 34which may be buckled around the leg above the knee, while straps 36secured to the leather pad 22 upon opposite sides thereof adjacent therear may be buckled around the leg just below the knee.

The operation of the device will be clear from the foregoing descriptionwithout further discussion.

From the foregoing description of the construction of my improveddevice, it will be seen that I have provided a simple, inexpensive andeflicient means for carrying out the objects of the invention, and whileI have particularly described the elements best adapted to perform thefunctions set forth, it is obvious that various changes in form,proportion and in the minor details of construction may be resorted to,without departing from the spirit or sacrificing any of the principlesof the invention.

Having thus described my invention what I claim as new is:

1. A device of the character described, comprising a main frameincluding spaced side members, anti-friction rollers ourn aled uponopposite ends of said main frame, a second frame pivotally secured tosaid main frame at the forward end thereof, and a flexible kneeling padstretched across and secured to the side members of each of said frames.

2. A device as described comprising a main frame having spaced sidemembers formed with legs at the forward and rear ends thereof,anti-friction rollers journaled at the lower portions of said legs, asecond frame pivotally secured to said main frame and including atransverse member and spaced side members, and a flexible kneeling padstretched across and secured to the side members of said frames.

3. A device as described comprising a main frame having rearwardlyconverging side members, terminating at their forward and rear ends indownwardly turned legs, a transverse rod connecting the lower portionsof the forward and rear legs respectively, a second inverted U-shapedframe pivotally mounted upon the forward end of said main frame and aflexible pad stretched across and secured to said main and secondframes.

4. A device as described comprising a main frame including side membersterminating each in a forward and a rear downwardly extending integralleg, the rear legs being relatively shorter than the forward legs, aninverted U-shaped frame pivotally supported upon said main frame at theforward ends of the side members thereof, a flexible kneeling padsecured to said frames, means for adjusting the tension of said pad andstraps for securing the device upon the knee of a wearer.

In testimony whereof I affix my signature.

HOMER K. DAVIDSON.
